9v 800 mAh lithium USB Rechargeable Battery

Shaped like a normal 9v battery this unit provides approximately 8.2v at full charge and operates like any normal 9v battery cell. The only exception is that this unit is rechargeable! Plug in a micro USB port in the back to charge with your computer, the side indicator will show you the current charge of the unit. Please do take precaution and prevention from wire shortage and paying attention to polarity. Lithium batteries can explode from pressure, heat or voltage short.

This battery holder connects 3 AAA batteries together in series for powering all kinds of projects. We spec'd these out because the box is slim, and 3 AAA's add up to about 3.3-4.5V, a very similar range to Lithium Ion/polymer (Li-Ion) batteries, plus it has a nifty on-off switch. That makes them ideal for use with 3.3V projects that have a 2-pin JST connector meant for one of our Li-Ion/Poly batteries. (Of course, you can't recharge them like Li-Ion/Polys, so don't try to plug this into one of our Li-Ion/Poly charger boards!) It also features an ergonomic belt clip for taking your power on the go.

In many applications, we will use lithium batteries as our power solutions. In this kind of application, the most two important things are the power boost and battery charger. These two points are a prerequisite for the system. The traditional power boost and battery charge circuit are usually divided into two separate parts, the circuit will be relatively cumbersome to build.
